Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in detail to belt conveying equipment used in the screen glass processing process, specifically to a belt conveyor used for intelligent baking processing of screen glass. Background Art

[0002] As a common and highly stable conveying equipment, belt conveyors are widely used in many fields. For example, they are used in processing procedures such as baking of screen glass panels. Their stable mechanical properties ensure the stable movement of the panels during the baking process. For example, in the prior art, a screen conveying device of an ultrasonic cleaning machine with a publication number of CN109335684B includes a cleaning cover, an arranging and pushing device in the cleaning cover, a feeding device and a control device. The cleaning cover is a long strip structure. The arranging and pushing device includes a pushing component for pushing the screen and a driving component for driving the pushing component to always maintain horizontal rotation in a vertical plane. The feeding device includes a lifting component for driving the screen to rise and a pushing component for pushing the screen onto the lifting component. The lifting component is arranged at one end of the cleaning cover and is located directly below the pushing component. The pushing component is arranged on the side of the cleaning cover and is close to the lifting component. The control device includes a controller and a sensor component electrically connected to the controller, which simplifies the equipment structure, reduces processing costs, and improves cleaning efficiency.

[0003] Another example is a glass processing synchronous belt conveyor device with a publication number of CN116891092A in the prior art, which includes a frame, bearings are sleeved on the top of both ends of the frame, and a conveyor belt is sleeved between the two bearings. In addition, two conveyor belts are provided and are symmetrical about the central axis of the frame, a bottom plate is welded to the bottom end of the frame, and a shovel plate is placed between the inclined plate and the bottom plate. The invention is convenient and quick to use, and can realize double synchronous belt transmission by setting two conveyor belts to form a blank unsupported space. When glass fragments appear, the fragments directly fall to the top of the bottom plate under the connecting line through the inclined plate, which effectively reduces the probability of glass fragments entering the cleaning machine, improves the linkage of the production line, and reduces downtime. At the same time, by driving the shovel plate, there is no need for manual pulling. The automated glass conveying equipment can be cleaned automatically and regularly, effectively avoiding the impact of workers' injuries on production at work and improving work safety.

[0004] Most of the solutions disclosed in the prior art are to improve the stability of transportation or facilitate the cleaning of the conveyor belt itself. However, the size of the glass sheets will vary depending on the size of the screen, especially different specifications of products in the same series. The sizes of the screen glass will often be quite different due to different specifications. A single conveyor belt has barriers in conveying glass of different specifications, resulting in higher processing costs. Summary of the invention

However, due to the different sizes of the screens, the sizes of the glass sheets will also be different, especially the different specifications of products in the same series, which often lead to large differences in the size of the screen glass due to different specifications. A single conveyor belt has barriers in conveying glass of different specifications, resulting in high processing costs.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a belt conveyor for intelligent baking processing of screen glass, comprising a belt body and a body for installing and driving the belt body, wherein the middle section of the belt body passes through the baking machine, and the upper end surface thereof is used to place the glass panel, and a supporting conveying mechanism is installed on the belt body, and the supporting conveying mechanism is used to carry the panel to move synchronously with the belt body, and the supporting conveying mechanism is also used to separate the belt body and the panel, and the supporting conveying mechanism also includes a negative pressure mechanism, and the negative pressure mechanism is used to maintain the stability of the panel in the horizontal direction.

[0007] Preferably, the supporting conveying mechanism comprises a column protruding from the surface of the belt body and the edge of the body, and the column is evenly and detachably installed in the reserved hole on the belt body.

[0008] Preferably, the negative pressure mechanism includes a negative pressure fan and a space formed by a belt body connected to its input end, and the space is connected to the hollow structure of the column. The top opening of the column is used for the negative pressure adsorption panel when the hollow structure is in a negative pressure state.

[0009] Preferably, the supporting and conveying mechanism comprises a round rod and a support plate rotatably mounted on the top of the round rod and horizontally distributed, wherein the bottom end of the round rod is also mounted on the belt body, and the support plate is connected to a pallet for supporting the panel via a cylinder.

[0010] Preferably, the negative pressure mechanism includes a suction hole opened at the center of the support plate and vertically penetrated, and a soft pad which also vertically penetrates the opening is arranged around the suction hole, and the suction hole is connected to the suction mechanism through a hollow structure in the sliding rod, and the top and bottom ends of the sliding rod are respectively connected to the support plate and the cylinder.

[0011] Preferably, the suction mechanism includes a valve plate slidably mounted inside the cylinder and a suction cavity above the valve plate, the space above the valve plate is connected to the suction hole through an opening in the lower half of the sliding rod and a hollow structure inside the sliding rod, wherein the middle section of the sliding rod is vertically elastically slidably mounted on the top wall of the cylinder.

[0012] Preferably, a top plate is slidably mounted on the support plate via a vertical rod with a spring, and the top plate is used to gradually bring the panel and the support plate closer when the panel is placed on the support plate, and a blowing hole is provided on the side of the support plate on the end surface;

[0013] Preferably, the blowing hole is used to blow out airflow and act on the lower end surface of the panel when the panel is placed on the supporting plate, and the blowing hole is connected to the blowing mechanism.

[0014] Preferably, the blowing mechanism includes a valve plate and a blowing cavity below the valve plate, the input end of the blowing cavity is a one-way air port, and the output end is connected to the internal cavity of the support plate and the blowing hole through a soft air pipe which is also provided with a one-way valve.

[0015] Preferably, the interior of the valve plate is also a hollow structure, the lower opening of the hollow structure is connected to the movable plate through an annularly distributed elastic layer, and the upper surface of the movable plate is connected to a metal strip of a memory alloy material;

[0018] 1. The structural design of the support plate and the suction hole enables the panel to be placed on the support plate and then driven by its own gravity to move down synchronously with the support plate, the slide bar and the valve plate, so that the internal space of the upper half of the cylinder is in a negative pressure state. The connection between the space and the suction hole is then used to achieve rapid adsorption and positioning of the panel, thereby increasing the stability of the panel, especially the large-sized panel, during movement, and ensuring that the panel can be smoothly taken out and separated after baking.

[0019] Furthermore, the structural design of the top plate on the support plate can effectively buffer the pressure or impact force generated by the placement of the panel by utilizing its own elastic characteristics, and the setting of the side blowing holes can utilize the movement of the valve plate to simultaneously generate an airflow conveying effect and effectively clean the panel with airflow;

[0020] 2. The structural design of the metal strips and movable plates enables the valve plate to not only transport airflow through its own movement, but also utilize the temperature-sensitive deformation characteristics of the metal strips inside it to deform in the high-temperature section and store high-temperature airflow inside the valve plate, and release the airflow in the low-temperature section and contact with the panel to effectively preheat the panel surface, thus saving energy and being more environmentally friendly.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 10 , the present invention provides the following technical solutions:

[0034] Embodiment 1: In order to solve the problems existing in the prior art, the following solution is disclosed, which can be referred to Figure 1 , including a belt body 1 and a body 2 for installing and driving the belt body 1 to operate, wherein the middle section of the belt body 1 passes through the baking machine, and the upper end surface thereof is used to place the glass panel, and a supporting conveying mechanism is installed on the belt body 1, and the supporting conveying mechanism is used to carry the panel and move synchronously with the belt body 1, and the supporting conveying mechanism is also used to separate the belt body 1 and the panel, and the supporting conveying mechanism also includes a negative pressure mechanism, and the negative pressure mechanism is used to maintain the stability of the panel in the horizontal direction, and the supporting conveying mechanism includes a column 3 protruding from the surface of the belt body 1 and the edge of the body 2, and the column 3 is evenly and detachably installed in the reserved hole on the belt body 1, and the negative pressure mechanism includes a negative pressure fan and a space formed by the belt body 1 connected to its input end, and the space is connected to the hollow structure of the column 3 The top opening of the column 3 is used for negative pressure adsorption of the panel when the hollow structure is in a negative pressure state. When the panel is placed on the top of the column 3, multiple evenly distributed columns 3 can give way to the top of the belt 1. When the width of the panel is greater than the width of the belt 1, the belt 1 can also transport the panel. The use of the negative pressure mechanism can make the movement of the panel more stable and avoid unstable distribution in the baking area due to heat flow. The startup of the negative pressure mechanism mainly depends on the negative pressure fan. The relatively sealed space formed by the belt 1 and the body 2 is connected to the fan. After the fan is started, the space and the hollow structure of the column 3 connected thereto will be in a negative pressure state. Therefore, the panel covered on the top opening will be relatively stably adsorbed by the negative pressure on the top of the column 3.

[0035] Embodiment 2: Also to solve the problems existing in the prior art, this embodiment discloses a support and conveying solution different from the above embodiment, specifically as follows Figure 2-Figure 3As shown, the supporting and conveying mechanism includes a round rod 4 and a support plate 5 rotatably mounted on the top of the round rod 4 and horizontally distributed, wherein the bottom end of the round rod 4 is also mounted on the belt body 1, and the support plate 5 is connected to a support plate 7 for supporting the panel through a cylinder 6, which is also a support scheme protruding from the surface of the belt body 1. The support plate 5 in this scheme is able to rotate around the round rod 4. The advantage of such a setting is that when the panel is too large, the support area formed by the left and right symmetrically distributed support plates 5 can be adjusted by rotating and adjusting the horizontal angle of the support plate 5. When the support plate 5 follows the round rod 4 to rotate to the space below the belt body 1, the support plate 5 will also rotate around the round rod 4 under the action of the side wall limit of the body 2, ensuring that the rotation adjustment of the support plate 5 will not affect the normal operation of the belt body 1.

[0036] In this embodiment, another negative pressure solution is disclosed, which is more energy-saving and environmentally friendly than the first embodiment, and the use cost is relatively low. For details, please refer to Figure 4-Figure 7 The negative pressure mechanism includes a suction hole 8 which is opened at the center of the support plate 5 and passes through vertically. A soft cushion which also passes through the opening vertically is arranged around the suction hole 8. The suction hole 8 is connected to the suction mechanism through the hollow structure in the slide bar 9. The top and bottom ends of the slide bar 9 are respectively connected to the support plate 5 and the cylinder 6. The suction mechanism includes a valve plate 14 slidably mounted inside the cylinder 6 and a suction cavity 15 above the valve plate 14. The space above the valve plate 14 is connected to the suction hole 8 through an opening opened in the lower half of the slide bar 9 and the hollow structure inside the slide bar 9. The middle section of the slide bar 9 is vertically elastically slidably mounted on the top wall of the cylinder 6. When the panel is placed on the support plate 7, it is affected by gravity. The support plate 7 will be compressed and the valve plate 14 will be driven to move downward through the slide bar 9. At this time, the internal space of the cylinder 6 above the valve plate 14 will be in a negative pressure state, and the space is connected to the suction hole 8 through the slide bar 9. Therefore, when the support plate 7 moves downward under gravity, the suction hole 8 will be in a negative pressure state. In this way, the panel will be in a relatively stable state in the horizontal direction, and the heat flow in the baking machine will not cause the panel to shake and affect the processing quality. Another effect is that the separation of the panel is more convenient. It only needs existing material taking equipment such as suction cups or manipulators to drive the panel to move upward a certain distance, and the valve plate 14 will move up synchronously, and it will contact the negative pressure state, so the panel will be separated more smoothly.

[0037] The technical problem to be solved in this embodiment is the stability problem during the panel placement process. Specifically, the placement by manual or mechanical hands is prone to damage due to the collision and scraping between the wide characteristics of the panel and the conveyor. The reason for this problem is that manual operation is unstable or the accuracy of the mechanical hand is reduced. The solution in this embodiment is to provide buffer protection for the panel from the perspective of the conveyor belt. Specifically, Figure 4-Figure 7In the scheme shown, a top plate 10 is slidably mounted on the support plate 7 through a vertical rod 11 with a spring. The top plate 10 is used to gradually bring the panel and the support plate 7 closer when the panel is placed on the support plate 7, and a blowing hole 12 is provided on the side of the support plate 7, which is opened on the upper end surface of the support plate 7. The blowing hole 12 is used to blow out air flow and act on the lower end surface of the panel when the panel is placed on the support plate 7, and the blowing hole 12 is connected to the blowing mechanism, and the blowing mechanism includes a valve plate 14 and a blowing cavity 16 below the valve plate 14. The input end of the blowing cavity 16 is a one-way air port, and the output end is connected to the one-way air port through the same device. The soft air pipe 13 with a one-way valve is connected to the internal cavity of the support plate 7 and the blowing hole 12. When the panel is placed on the support plate 7, it will first contact the top plate 10 with a smaller contact area at the top. The elastic structure of the top plate 10 itself will also buffer the possible impact force through elastic movement. At the same time, when the valve plate 14 moves downward, the airflow in the blowing cavity 16 will also enter the air pipe 13 and finally blow out from the blowing hole 12, thereby realizing airflow-type non-contact cleaning of the lower end surface of the panel to avoid possible dust and impurities from polluting the baking processing space.

[0038] Embodiment 3: In this embodiment, a relatively unique solution is disclosed. The effect of this solution is to use the unique working environment of the conveyor to preheat the panel. The reason for preheating is to achieve better results in the subsequent formal baking. In addition to preheating, it can also increase the heating effect of the panel in the baking space, assist the panel coating to solidify quickly, and improve the molding quality of the panel. Please refer to Figure 8-Figure 10 The interior of the valve plate 14 is also a hollow structure. The lower opening of the hollow structure is connected to the movable plate 17 through a ring-shaped elastic layer 18, and the upper surface of the movable plate 17 is connected to a metal strip 21 of a memory alloy material. The two ends of the metal strip 21 are fixed to the inner wall of the valve plate 14. At the same time, the one-way input end of the hollow structure is connected to the external space of the cylinder 6 through a vertical pipe 19, and the one-way output end is connected to the air pipe 13 through a connecting pipe 20. Since the space temperature of the baking process is high, after reaching the threshold temperature, the metal strip 21 of the memory alloy will bend downward accordingly and drive the movable plate 17 downward. During this process, the space of the blowing cavity 16 is compressed, and the air flow will continue to blow out from the blowing hole 12. Since it is already in the baking space at this time, the air flow under the panel will be accelerated to promote full contact between the heat and the panel, and the internal space of the valve plate 14 will expand and guide the hot air flow in the baking space to the inside of the valve plate 14. When the supporting moving mechanism is separated from the panel and returns to the placement station from the bottom of the baking space again, the metal strip 21 will restore its deformation, so the movable plate 17 moves upward and blows out the previously inhaled hot air flow from the blowing hole 12, and preheats the panel that has not entered the baking space.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
